Abstract

A hand gesture control system to be operated via hand gestures to receive a call from a mobile phone includes: a casing; a control unit installed inside the casing; a hand gesture recognition unit installed inside the casing, including an image capturing module and a hand gesture recognition module, wherein the image capturing module captures an image of a hand gesture of a user and transmits to the gesture recognition module for comparison, which feeds back an operation instruction to the control unit corresponding to the comparison; a wireless transmission unit communicates with the mobile phone via a wireless communication protocol for establishing communication between the mobile phone and the control unit; a microphone disposed at an exterior of the casing in order to receive a user'"'"'s voice; and a loudspeaker disposed at an exterior of the casing in order to output the user'"'"'s voice from the microphone.

Claims

1. A modular hand gesture control system adapted to be operated via hand gestures in order to receive a call from a mobile communication device and/or to activate a network operation, comprising:

a casing defining a receiving chamber;

a control unit installed inside said receiving chamber of said casing;

a hand gesture recognition unit installed inside said receiving chamber of said casing, including an image capturing module and a hand gesture recognition module coupled electrically to said image capturing module and said control unit, wherein said image capturing module is adapted to capture an image of a hand gesture of a user and transmits said image to said hand gesture recognition module for comparison, which feeds back an operation instruction to said control unit corresponding to said comparison;

a wireless transmission unit installed inside said receiving chamber of said casing and coupled electrically to said control unit, wherein said wireless transmission unit is configured to communicate with the mobile communication device by using a wireless communication protocol to establish communication between the mobile communication device and the control unit;

a microphone coupled electrically with said wireless transmission unit, wherein said microphone is disposed at an exterior of said casing in order to receive a user'"'"'s voice; and

a loudspeaker coupled electrically with said wireless transmission unit, wherein said loudspeaker is disposed at an exterior of said casing in order to output said user'"'"'s voice received from said microphone.

2. The modular hand gesture control system according to claim 1, wherein said control unit is selected from a group consisting of a MCU (Microcontroller Unit) and a CPU (Central Processing Unit).

3. The modular hand gesture control system according to claim 1, wherein said image capturing module is a camera.

4. The modular hand gesture control system according to claim 1, wherein said wireless communication protocol is selected from a group consisting of Bluetooth, Infrared (IR), Near Field Communication (NFC), Wireless Local Area Network (WLAN), Wireless Gigabit Alliance (WiGig), ZigBee, Wireless USB, Ultra Wide Band (UWB), Wi-Fi and a combination of at least two thereof.

5. The modular hand gesture control system according to claim 1, further comprising a power source management unit to supply electrical power for operation of the hand gesture control system.

6. The modular hand gesture control system according to claim 5, wherein said power source management unit is selected from a group consisting of a rechargeable battery and an external power source.

7. The modular hand gesture control system according to claim 6, wherein said external power source is adapted to be connected via a USB connection port.

8. The modular hand gesture control system according to claim 1, wherein said hand gesture recognition module has nine sets of built-in hand gesture, each built-in hand gesture set represents and corresponds to an operation instruction.

9. The modular hand gesture control system according to claim 8, wherein said hand gesture recognition module includes a built-in comparison module stored with nine sets of hand gestures, said built-in comparison module compares said image of said hand gesture of said user with a respective one of said plurality of hand gestures in said built-in comparison module.
